Abstract:
The present invention relates to a method for enabling the efficient communication of machine-type communication (MTC) equipment by selecting a connection with a base station during a first allowed time period in a mobile communication system using the MTC equipment, and to a device for same. With regard to an example of the present invention, a communication method for MTC equipment in a wireless mobile communication system may include: receiving a first message, including information regarding the first allowed time period, from a network through dedicated signaling; transmitting or receiving data to/from the network during the first allowed time period included in the first message; and receiving, from the network, a second message including information regarding a second allowed time period different from the first allowed time period.
